BOTTLE-VENT.

Specification of Letters Patent.

Patented Oct. 23, 1917.

Application filed January 19, 1917. Serial No. 143,314.

To all whom it may concern:

Be it known that I, VERN I. MosER, a citizen of the United States, residing at IVichita, in the county of Sedgwick and State of Kansas, have invented new and useful Improvements in Bottle-Vents, of which the following is a specification.

This invention relates to devices attached to bottles and designed for the purpose of admitting air to the bottle when the contents thereof are poured out, thereby facilitating the discharge and causing the liquid to run in a steady stream from the bottle.

The invention has for its object to provide a novel and improved vent deviceof the kind stated, and means for supporting the same in operative position in the bottle as will be described hereinafter in detail, and in order that the invention may be better understood reference is had to the accompanying drawing forming a part of this specification.

In the drawing,

Figure 1 is a vertical section of the device in position for use; 1

Fig. 2 is a horizontal section on the lin 22 of Fig. 1, and

Fig. 3 is a perspective view of the device removed from the bottle.

The device is designed more particularly for application to large bottles such as are used for holding distilled or mineral water. With a bottle of this kind it is usually impossible to pour out the liquid in a steady stream without an air vent of some sort, and in order to provide a vent device which can be easily attached to and removed from the bottle, the present invention has been designed.

The vent device comprises a rigid tube 5 of metal or other suitable material, which is curved in the direction of its length and open at both ends. A fragment of the bottle to which the vent tube is applied is shown at 6, the same being provided with a neck 7 in which the tube is held by a device to be presently described. The tube is curved so that it may pass down into the body of the bottle from the neck thereof in a sidewise direction, its inner end terminating close to the side of the bottle body. The diameter of the tube is such that it takes up but little space in the bottle neck, and it also seats close to the inner surface of the neck, in

and secured tothe tube in any suitable mannor a short distance below the outer end thereof: The spring projects from opposite sides of the tube, said projecting ends forming two resilient clamping members 8 which are curved in the direction of their length.

The normal tendency of the members 8 is to spread, and before they can be inserted in the bottle neck 7 it is necessary that they be contracted, and when they are released they expand and seat against the inner surface of the bottle neck, as shown in Fig. 2, their expanding tendency causingthem to bind and frictionally engage said surface to firmly hold the tube in place. The tube 5 is thus securely held in operative position, and at the same time it is readily removable from the bottle.

In order to guard against the slippage of the tube 5 downward in the bottle neck 7, the outer end of the tube has an outstanding flange or lip 9 which seats on a shoulder 10 in the bottle neck at the mouth thereof.

I claim 1. A vent device comprising a tube open at its ends, and resilient holding members carried by the tube adjacent to one end thereof, said members extending laterally from opposite sides of the tube and having a normal tendency to expand.

2. A vent device comprising a tube open at its ends, and resilient holding members carried by the tube adjacent to one end thereof, said members extending laterally from opposite sides of the tube, and having a normal tendency to expand, and curved in the direction of their length.

3. A vent device comprising a tube open at its ends, and resilient holding members carried by the tube adjacent to one end thereof, said members extending laterally from opposite sides of the tube andhaving a normal tendency to expand, and an outstanding retaining flange at the aforesaid end of the tube.

In testimony whereof I affix my signature.
